The Order of the Crown of Westphalia (German: Orden der Westfälischen Krone) was instituted in Paris on 25 December 1809 by King Hieronymus I of Westphalen, better known as Napoleon's brother Jérôme Bonaparte.

On July 7, 1807, Napoleon I gave his youngest brother Jérôme Bonaparte the Kingdom of Westphalia, created from scratch from hitherto independent German states.

Finally, on December 25, 1809, "with imperial authorization," the king was able to sign the royal decrees of creation of the Order of the Crown of Westphalia.

A new decree was drawn up, issued on April 25, 1810, which definitively fixed the composition of the insignia, with a general outline close to that of the Order of the Iron Crown.

Above a crown bandeau, we find the symbolic elements of the previous badge: heraldic animals, snake in bail, and of course the imperial eagle encroaching a lightning.

The decoration is composed of a crown with eight gold florets without apses, placed on a blue enameled headband, on which are written in Roman letters in gold and in all its periphery, the motto of the order): "CHARACTER UND AUFRICHTIGKEIT "(in French:" Honesty and character "), as well as the date of its founding:" ERRICHTET DEN XXV DEC M. DCCC IX ".

The decoration is suspended from a big-blue ribbon moiré, by a ring having the shape of a snake biting its tail, symbol of the immortality.

The reverse of the cross is absolutely similar, with this difference only, that there is on the eagle and lion backed, an azure shield on which are the Roman letters "H N" intertwined.
